REGISTERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 611,139, dated September 20, 1898.

Application filed March 23, 1898.

To all whom it may concern:

Be it known that I, LEONARD DENVER ORR, of Pegram, in the county of Greene and State of Illinois, have invented a new and Improved Registering Apparatus, of which the following is a full, clear, and exact description.

This invention is a registering apparatus of that class in which a series of registeringdisks is mounted on a common axis, the said disks being driven one from the other, so that a total number will be shown.

This specification is the disclosure of one form of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a partial section of my invention. Fig. 2 is a face view of one of the registering-disks, to be hereinafter described. Fig. 3 is a face view of one of the transmission-disks, to be hereinafter described. Fig. 1 is a face view of a second of the transmission-disks, to be hereinafter described. Fig. 5 is a face view of one of the stop-plates, to be hereinafter described. Fig. 6 is a face view of a second of the stop-plates, to be hereinafter described. Fig. 7 is an end elevation of one of the dogs, to be hereinafter described; and Fig. 3 is a sectional view thereof.

The registering apparatus may be mounted in a stationary casing 10, having an orifice (not shown) for exposing the numbers. Revolubly journaled in the casing and extending through the same is the shaft 11, the movement of which is to be indicated. Mounted loosely on the shaft 11, at one end of the easing 10 and within the same, is a registeringdisk 12, which has a pinion-gear 13 fast thereto. The gear 13 meshes with a gear 14, in rigid connection with another gear 15, both carried loosely on a stub-shaft 16, supported by the casing 10. A gear 17 is keyed to the shaft 11 and meshed with the gear 15. This arrangement of gears drives the registeringdisk 12 from the shaft 11. The registeringdisk 12 may be driven at any speed relative to that of the shaft; but it is preferred that the ratio of movement be ten revolutions of the disk to one revolution of the shaft. The

registering-disk 12 is provided with ten num- Serial No. 674,896. (No model.)

hers on its face, indicating the units of the numbers shown by the apparatus. The ratio of movement of the various parts is such that each movement from one figure'to another on the disk 12 shall indicate one movement or one rotation of the part the movements of which'are to be counted.

Located snugly against the inner face of the disk 12 and held fast by the casing 10 is a stop-plate 18, through which passes loosely the shaft 11. Mounted loosely on the shaft 11 and lying snugly against the inner face of the stop-plate 18 opposite the disk 12 is a registering-disk 19, a face view of which is given in Fig. 2. This disk is provided with a circular concavity 20 in its right-hand face and concentric to theshaft 11. Keyed to the shaft 11 and situated within the concavity 20 is a transmission-disk 21, a face view of which is given in Fig. 3. The disk 21 is provided in its periphery with two oppositely-disposed notches 22 and 22. The notch 22 is designed to receive a stud 23, formed on the disk 19 and projecting into the concavity 20 thereof. Contained within the notch 22*,which receives the stud 23, are two expansive spiral springs 24, that bear, respectively, against opposite sides of the stud 23 and that respectively engage the end walls of the said notch 22. These springs, with their stud 23, tend to keep the disk 19 at a certain position relative to the disk 21, and consequently to the shaft 11, from which position the disk 19 may depart by overcoming the force of the springs 24. This independent movement of the disk 19 with relation to the disk 21 is limited by the end walls of the notch 22, which receives the stud and springs. The disk 19 is provided at the concavity 20 and near the periphery thereof at a point opposite the stud 23 with a counter-cavity 25, which by reason of its location relative to the stud 23 is in immediate proximity to the notch 22 of the transmission-disk 21, which notch 22 is opposite the notch receiving the stud 23. This counter-cavity 25 receives fixedly a block 26, which lies flush with the bottom of the concavity 20. Sliding in the block 26 transversely of the plane of the disk'lf) is a dog 27, pressed outward from the block by an expansive spring 28 contained therein. Mounted to rock in the block 26 and having each an arm projected normally beyond the right-hand or end face thereof are two elbow-levers 29, the inner arms of which are loosely connected with the dog 27. The dog 27 by the action of the spring 28 is capable of extending, as shown in Fig. 1, through the adjacent notch of the transmission-disk 21 and into any one of the circular series of orifices 30 in the stopplate 18. When the dog 27is so engaged with the plate 18, the registering-disk 19 is held rigid with the casing. When the dog 27 is withdrawn from its engagement with the stop-plate 18, the action of the transmissiondisk 21 will cause the disk 19 to turn on the shaft 11. When the dog 27 is pushed out ward to engage the plate 18, the outer arms of the elbow-levers 29 project into the adjacent notch 22 of the transmission-disk 21. Now as the shaft 11 turns the disk 21, moving therewith, will compress one of the springs 24 (the disk 19 being held as before explained) and the transmission-disk 21 will also engage (at one end wall of the adjacent notch 22) the outer arm of one of the elbow-levers 29, so that said elbow-lever will be rocked inward to push the dog 27 into the block 26 and'withdraw the dog completely into the block, leaving it out of engagement with the plate 18. This movement being effected the compressed spring 24 will assert itself to impart to the disk 19 a spasmodic forward movement, thus disengaging the said elbow-lever from the wall of the adjacent notch 22 in the disk 21 and permitting the spring 28 to throw the dog 27 back to its outer position, whereupon the dog' enters the contiguous orifice 30 of the plate 18 and the movement of the disk 19 is again stopped. The shaft 11, however, revolves continuously and at the immediatelysucceeding instant the disk 21 will again compress one of the springs 24 and will again withdraw the dog 27, whereupon the disk 19 is given a second spasmodic movement, to be again arrested by the return of the dog 27 to the next orifice of the plate 18. This movement continues without intermission during the entire operation of the apparatus. The shaftll turns continuously and the disk 19 has a spasmodic though practically continuous rotary movement. This disk 19 is provided with numbers on its face which indicate'the tens in the sum indicated by the machine. According to this arrangement the eventual movement of the disk 19 is exactly the same as that of the shaft 11that is to say, at the end of the operation the disk 19 has turned as many revolutions as the shaft 11 has turned.

Fast in the casing 10 and snug against the left-hand face of the disk 19 is a stop-plate 31, a face view of which is given in Fig. 6. This plate 31 is like the plate 18 both in construction and arrangement, except that the plate 31 is provided, in addition to its circular series-of orifices 32, with an arc-shaped slot 33, locatedinward of the series of notches 32-and having a length equal to one-fifth of the circumference of a circle struck from the center of the shaft 11, which shaft passes loosely through the plate 31. Seated and held rigidly in the disk 19 is a block 33, which carries a dog and its actuating devices similar to the dog 27 shown in Figs. 7 and 8. This dog is capable of being retracted entirely into the block 33 or of extending out- Ward from the block through the slot 33 of the plate 31 and into any one of the orifices of a circular series of orifices 34, which are formed in a transmission-disk 35, a face view of which is given in Fig. 4. The transmission-disk 35 is provided with peripheral notches 36 and 36, similar tothe notches 22 and 22 of the disk 21, and is mountedloosely on the shaft 11; The disk 35 is therefore similar to the disk 21, except that it has the orifices 34and that the disk 35 is loose on the shaft. The block 33, with its dog, moves with the disk 19. Assuming that the parts be in the position shown in Fig. 1-which is to say, with the dog of the block 33 extended through the slot 33 and through one of the orifices 34the block 33 in moving will through the medium of its dog transmit to the disk 35 a fragment of a rotation. As the block 33, with its attached parts, continues to move one of the bell-crank levers in said block will engage with one wall of the orifice 32 in the stop-plate 31, whereupon the dog of the block 33 will be thrown into the block in the manner explained with reference to the dog 27. This dog of the block 33 will now be entirely disengaged both from the plate 31 and the disk 35, and consequently the block 33 will no longer transmit movement to the disk 35; but the disk 19 may continue its rotary movement without influencing the disk 35, since the end of the dog in the block 33 then simply bears against the right-hand face of the disk 31 and maintains this contracted and inactive position until a nearly complete revolution of the disk 19 has been performed, whereupon the dog of the block 33, upon again reaching the slot 33 in the plate 31,will be permitted to slip into said orifice and also to engage with one of the orifices 34 in the transmission-disk 35. This causes another fragmentary movement of the disk 35,which is exactly as that before described and which is arrested as the block 33 approaches the other end of the slot- 33, and by engagement with the wall thereat the dog of the block 33 is retracted and rendered inactive. By these means I impart to the transmission-disk 35 a step-by-step rotary movement derived from the disk 19. According to the relative arrangement of the orifices 33 and 34 and of the slot or orifice 32 the disk 35 is turned one-tenth of a revolution for every single revolution of the disk 19.

Lying snugly against the left-hand face of the stop-plate 31 is a registering-disk 37,

which is mounted loosely on the shaft 11 and whichhas a concavity similar to the concavity 20 of the disk 19. This concavity of the disk 37 receives the transmission-disk 35. The registering-disk 37 has a counter-cavity similar to the counter-cavity 25 of the disk 19, wherein is fixed a block 38, containing a dog, all of which is similar to the block and dog of Figs. 7 and 3. The disk 37 is also provided with a stud projecting into the concavity thereof, which stud is similar to the stud 23 of the disk 19, and which therefore projects into the notch 36 of the disk 35 and is pressed on each side by an expansive spring similar to the springs 21, before described. All of these parts being thus arranged and the disk 35 being given a step-by-step rotary movement such disk imparts to the disk 37 a step by-step rotary movement, which, though not in absolute unison with the movements of the disk 35, is nevertheless equivalent thereto, the movements of the disk 37 being dependent upon the spasmodic action of the springs of the disk 37, as has been already explained in reference to the disk 19. Tracing the movements so far described it will therefore be seen that while the disk 19 turns continuously with a jumping or spasmodic movement equivalent to that of the shaft 11 the disk 37 has a step-by-step movement equal to one-tenth of a revolution, each step being imparted when a certain revolution of the disk 19 has been effected. The disk 37 is provided with numbers which represent the hundreds on the sum indicated by the apparatus. The dog of the block 38 projects through the notch 36 in the transmissiondisk 35 and beyond the said disk into any one of the orifices in the stop-plate 31. The function of the dog of the block 38 is to hold the disk 37 stationary when the disk is not being actuated by the disk 35. When the disk 35 moves to turn the disk 37, the disk acts on the devices of the block 38 to with draw the dog thereof from engagement with the stop-plate 31, and consequently the disk 37 is permitted to move. The instant that the disk does move the conditions which effect the withdrawal of the dog of the block 38 are destroyed and the said dog by an action of its spring again enters one of the orifices 32 in the plate 31, whereupon the movement of the disk 37 is arrested and the disk is held until the disk 35 again moves, first to withdraw the dog of the block 33 and next to compress one of the springs of the disk 37, which spring when compressed throws the disk 37.

Ihave now explained the essential elements of my invention. The number of disks may be increased indefinitely to enlarge the capacityof the apparatus; but to the operation thereof only three registering-disks and the stop-plates and transmission-disks thereof are essential. Tracing the simultaneous movements of these parts it will be seen that the turning of the shaft 11 results, first, in the rotation of the disk 12 at a speed tenfold that of the shaft 11. This disk 12 therefore is ever-changing in its indications and shows the units or smallest factors of. the number being indicated. Next in movement comes the disk 19, which turns spasmodically, but with the same speed as the shaft 11, to show the tens of the number indicated. The movement of the disk 19 is effected directly from the shaft 11 by the action of the transmission-disk 21, as explained. Finally comes the hundreds-disk 37, which has the step-bystep movement, each step representing onetenth of a complete revolution and each step being effected when an entire rotation of the disk 19 has been made. The disk 37 is driven from the disk 19 through the medium, first in order, of the block 32 and its contained dog; next, of the transmission-disk 35, which is driven directly by the dog of the block 33 and,finally,through the medium of the springs contained in the disk 37, similar to the springs 24: of the disk 19, which springs of the disk 37 are compressed by the transmission-disk 35, then permitted to expand to directly influence the disk 37.

In Fig. 1 I have shown additional disks with their coacting parts, which I do not propose specifically to describe. It will suffice to say that each registering-disk as it proceeds toward the left of Fig. 1 represents an increased degree of the number indicated and that each disk is driven in the same manner as the disk 37which is to say, from the disk directly at the rightthrough the medium of blocks, such as the blocks 33, transmission-disks, such as the transmissiondisk 35, and springs, such as the springs of the disk 37.
